Question 6
A group of students conducts research on enzyme activity and collects the data shown in the graphs.
Which statement is supported by the evidence in the graphs?
a
The enzyme is very active at approximately 42°C and within a pH range of 2 to 6.
b
The enzyme functions well at a temperature of 35°C and would be active at any pH value.
c
The enzyme works best in a pH range of 6 to 8 and at a temperature of approximately 37° C.
d
The enzyme's activity is greatest at pH 7 and would not be affected by a change in temperature.
Question 7
Crystals of dye, when placed in a beaker of water, eventually spread evenly throughout the water. This is an example of
a
active transport.
b
phagocytosis.
c
diffusion.
d
osmosis.
Question 8
A group of students are conducting an experiment. Since potatoes contain both sugar and water, the students use them in the experiment. The students cut six equal cubes of potato and weigh them. They place the six cubes into six different beakers containing different concentrations of sugar solutions, then weigh each potato cube after 24 hours and calculate the percent change in mass. The graph below shows the result of their experiment.
Which of the statements below is a valid conclusion about this experiment?
a
The lower the concentration of sugar, the more likely the potato will gain mass.
b
The higher the concentration of sugar, the more likely the water concentration will be at equilibrium.
c
The higher the concentration of sugar, the more likely the potato will gain mass.
d
The lower the concentration of sugar, the less likely the potato will gain mass.
